NAME¶
Image::ExifTool::MWG - Metadata Working Group support
SYNOPSIS¶
# enable MWG Composite tags
use Image::ExifTool::MWG;
Image::ExifTool::MWG::Load();
# enable MWG strict mode
$Image::ExifTool::MWG::strict = 1;
# disable MWG strict mode
$Image::ExifTool::MWG::strict = 0;
DESCRIPTION¶
The MWG module contains Composite tag definitions which are designed to simplify
implementation of the Metadata Working Group guidelines. These special MWG
Composite tags are enabled by calling the
Load() method:
use Image::ExifTool::MWG;
Image::ExifTool::MWG::Load();
By default, loading the MWG Composite tags enables "strict MWG
conformance" unless previously enabled or disabled by the user. In this
mode, ExifTool will generate a Warning instead of extracting EXIF, IPTC and
XMP from non-standard locations. The strict mode may be disabled or enabled at
any time by setting the MWG "strict" flag to 0 or 1. eg)
$Image::ExifTool::MWG::strict = 0;
This module also contains the MWG XMP tags which are loaded automatically by
ExifTool as required, and are independent of the MWG Composite tags which must
be loaded explicitly as described above.
